UNITED STATES PATENT OFFICE,

CYRUS B. BALDWIN, OF CINCINNATI, OHIO.

CORN-SHELLER.

Specification of Letters Patent No. 2,718, dated July 16, 1842.

To all whom it may concern:

Be it known that I, CYRUS B. BALDWIN, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and Improved Machine forshelling and WVinnowing Corn, and that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, making a part of this specification, in which Figure 1, is aside elevation; Fig. 2, a section; Fig. 3 parts detached.

In an oblong frame (a) formed of four posts with the necessary crossties I hang a vertical runner or wheel (5) having teeth projecting fromone fan; this wheel is made and driven like those in common use of asimilar description the bearings being in the upper cross ties of theframe; on the end of the shaft opposite the driver are fixed two pulleys('0, cZ,)the largest of which (0,) is connected with a pulley on theshaft of the fan wheel marked (a) which is placed in the lower and frontend of the frame; this fan is constructed in the usual manner having acase surrounding it, and a trunk (f) for directing the blast toward theriddle or sieve hereafter described.

The stationary plate is in form the segment of a circle, about onequarter, having a flange (h) on its outer edge (g) which extends fromthe top down about two thirds the length of the plate more or less andprojects over the edge of the wheel; on the face of the plate (9) ribsare cast all converging toward a point near the center of the circle,two or three of these ribs being below the lower end of the flange sothat the cob will be easily freed from the machine; the space betweenthe ribs is hollowed out so as to free the cob and allow it to turnradially with the wheel as it falls, thus preventing its tendency to flyoff toward its periphery; the upper edge of the plate is turned outwardso as to form a hopper (i) into which the ears of corn are put; on theback of this stationary plate (g) above the cross tie when the plate isin place, are cast two projections (5) and on the cross tie is screwed apiece of iron the end of which next the plate is of the same shape asthese projections (07) and stands between them, a rod passing throughall and forming a joint; the lower end is thus allowed a vibratorymotion to and from the wheel; it is prevented from coming in contactwith the wheel by means of a wire staple (in) which is attached to aprojection on the lower end of the plate and embraces a pin on theframe; the plate is pressed forward by means of a spring (76) whichbears against its lower end; this spring is attached to the rear postand its force is regulated by means of a set screw (Z) passing throughthe lower cross tie just forward of it. The wheel is boxed in around thesides and top except where the hopper projects; under this wheel isplaced a shoe (am) slightly inclined downward at the rear end wherethere is a riddle (m) attached formed of straight wires runninglengthways for carrying off the cobs while the corn sifts through; belowthe riddle is a screen-board (n) slanting forward against which the windfrom the fan impinges blowing the hulls and chaff out of the machinebehind, while the clean corn is conducted down under the fan.

The shoe and riddle which are connected together are supported by ledgeson which they move; these are attached to the posts of the frame and mayhave friction rollers placed between them and the shoe if desirable; apit-man (0) is attached to the shoe near the forward end which isconnected with a crank (79) on. a shaft running across the front end ofthe machine; on the end of this shaft is a pulley ((7) which isconnected by a band with the pulley (d) on the wheelshaft.

VVhenthis machine is put in operation the corn is dropped into thehopper and falls against the wheel when it is instantly shelled passingby the several ribs of the stationary plate, the hollows between theribs facilitating the operation, till it falls onto the riddle, whichtogether with the shoe being shaken in a longitudinal direction throwsthe cob out of the machine, the corn at the same time falling throughand down the screen board, a current of wind being kept up by the fan itis cleaned from the chaff and other light stuff.

What I claim is my invention and desire to secure by Letters Patent isThe stationary plate (g) constructed in the manner described, incombination with the shelling wheel (6) as herein set forth.

CYRUS B. BALDWIN.
